Abstract

The flavor dependence of the naive time reversal odd ("T-odd'') parton distributions for $u$- and $d$-quarks are explored in the spectator model. The flavor dependence of $$h_{1}^{\perp}$$ is of significance for the analysis of the azimuthal $$\cos(2\phi)$$ asymmetries in unpolarized SIDIS and DY-processes, as well as for the overall physical understanding of the distribution of transversely polarized quarks in unpolarized nucleons. As a by-product of the formalism, we calculate the chiral-odd but ``T-even'' function $$h_{1L}^{\perp}$$ which enables us to present a prediction for the single spin asymmetry $$A_{UL}^{\sin(2\phi)}$$ for a longitudinally polarized target in SIDIS.

Final State Interactions, T-odd PDFs & the Lensing Function

Conference Leonard Gamberg, Marc Schlegel - AIP Conf.Proc.

It has been suggested that under certain approximations the Sivers effect can be described in terms of factorization of final state interactions and a spatial distortion of impact parameter space parton distribution; that is a convolution of the so-called lensing function and the impact parameter GPD E. In this approach the lensing function is calculated in a non-perturbative eikonal model. This enables a comparison between the a priori distinct Sivers function and the GPD E which goes beyond the discussion of overall signs.

Why most flavor-dependence predictions for nonleptonic charm decays are wrong: flavor symmetry and final-state interactions in nonleptonic decays of charmed hadrons

Conference Lipkin, H.J.

Nonleptonic weak decays of strange hadrons are complicated by the interplay of weak and strong interactions. Models based either on symmetry properties or on the selection of certain types of diagrams are both open to criticism. The symmetries used are all broken in strong interactions, and the selection of some diagrams and neglect of others is never seriously justified. Furthermore, the number of related decays of strange hadrons is small, so that experimental data are insufficient for singificant tests of phenomenological models with a few free parameters. The discovery of charmed particles with many open channels for nonleptonic decays hasmore »« less

Odd--even l-dependence of effective internuclear potential. [Shell models, phase shift]

Conference LeMere, M. ; Tang, Y.C. - AIP (Am. Inst. Phys.) Conf. Proc.; (United States)

An important finding from resonating-group calculations is that, as a consequence of the Pauli principle, the phase-shift behavior commonly exhibits an odd--even l dependence. A determination is made of the condition under which this odd--even l dependence is expected to be particularly prominent. For this purpose the structure of the resonating-group exchange-normalization kernel is examined in the general case of A + B scattering, where the nuclei A and B contain N/sub A/ and N/sub B/ (N/sub A/ > N/sub B/) nucleons, respectively, and are described by translationally invariant shell model functions in oscillator wells having a common width parameter.more » 3 references.
